10/10 service consistently. Seen a noticeable behavior change in my dog after the first training session and in all the sitting sessions after she’s only gotten better. Always get a lot of pictures and very flexible with pickup and drop off times. Able to fit you in on a tight schedule and it’s clear my dog likes him!

Nick at Big Nick K9 worked miracles with our five-year-old French Bulldog, Tessa. Tessa had always done well with visiting dogs, so we decided to rescue a three-year-old English Bulldog. Over time, however, Tessa developed severe resource guarding and became increasingly aggressive toward our new dog. We were heartbroken and had reached the point where we believed we would have to rehome one of our beloved pets. Then we found Nick. In just six weeks, Nick completely transformed Tessa's behavior. He helped eliminate her aggression and resource guarding while also teaching her to consistently follow commands. Just as importantly, he trained us, making sure we had the knowledge and tools to maintain her progress long after the training was over. Nick exceeded every expectation we had. Thanks to his expertise, patience, and dedication, our dogs now live together peacefully, and we were able to keep both of our beloved pets. We can't thank Nick enough and highly recommend Big Nick K9 to anyone dealing with challenging behavioral issues.
Nick did a great job training our puppy Labrador Mandy! He taught us how to reinforce his training at home so we would have success, continuing this at home is vital. Nick is always available to answer any questions and his knowledge is evident when you see him training the dogs.
I can’t recommend Nick enough! We sent our one-year-old English Cream Golden Retriever, Huck, to him for training, and the transformation has been incredible.

I can’t recommend Nick enough! We sent our one-year-old English Cream Golden Retriever, Huck, to him for training, and the transformation has been incredible. From the beginning, Nick was professional, knowledgeable, and genuinely cared about making sure Huck was successful. He didn’t just train our dog—he taught us how to continue reinforcing everything at home so we could maintain the progress. Huck came home more confident, better behaved, and so much more enjoyable to take anywhere. Even friends and family have said he is a completely different dog from before training to after training. One thing that really stood out was the communication throughout the process. We received regular updates, photos, and videos, which gave us so much peace of mind and let us see all the progress Huck was making. It was obvious he was being well cared for, loved, and treated like family. I’ll also admit that before training, I was very hesitant about e-collars and prong collars because I’d only ever heard horror stories. Nick took the time to educate us on how they’re meant to be used properly—as communication tools to reinforce both good choices and unwanted behaviors, never as punishment. He answered every question we had and made sure we were comfortable before using them. Seeing the results firsthand completely changed my perspective. When used correctly, they are incredibly effective and allow for clear, consistent communication with your dog. Nick also went above and beyond for our family. We were leaving the country while Huck was in training, and our dogsitter for our six-year-old Golden Retriever unexpectedly fell through. Without hesitation, Nick welcomed our older dog into his home so both of our boys could stay together. Knowing they were happy, safe, and so well cared for while we were away gave us incredible peace of mind, and it’s something we’ll never forget. Even after Huck came home, the support didn’t stop. Nick continued checking in to see how Huck was progressing, answered our questions, and even offers follow-up sessions in your own home so your dog can continue learning in their natural environment. That level of dedication is rare. If you’re looking for someone who is patient, trustworthy, incredibly knowledgeable, and genuinely passionate about dogs, Nick is your guy… I am convinced he’s a dog whisperer or magician! The investment was worth every penny, and I would recommend him without hesitation to anyone looking for a trainer. Thank you, Nick, for everything you’ve done for Huck—and for us!

We had a very positive and life-changing experience with Big Nick K9 training. Our 3 dogs were all with Nick for 6 weeks, and we couldn’t be happier with the progress they made. Their listening skills, and overall behavior are greatly improved, and they are easier to manage as a pack. Nick is patient, and explains his methods clearly, and, as an added benefit, all of our pups adore him! We would highly recommend his services.
